[0002] Steel plates are flat steel materials that are cast from molten steel and pressed after cooling. With the development of science and technology, steel plates are mainly used in the automotive industry, aviation industry, electrical industry, mechanical industry and other fields. In the actual production process, steel plates need to be transported, so lifting equipment is required to lift and transport the steel plates. Thin steel plates (hereinafter referred to as "thin plates") are a type of steel plate. There are two ways to lift them after bundling: one is to transport them directly using a forklift; the other is to lift them using an overhead crane clamp. However, for these two methods of lifting thin plates, thin plates are prone to falling, breaking or deforming during the lifting process, resulting in cargo damage. The cargo damage rate of these two lifting methods is relatively high, and the safety risks are relatively large. Utility Model Content

[0014] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a hanger for transporting steel plates of the present invention in conjunction with the accompanying drawings.

[0015] like Figure 1-2As shown, the sling for transporting steel plates of the present invention includes a crossbeam 1, a lifting ring 2 and a lifting arm 3. The lifting ring 2 is arranged above the crossbeam 1, and the sling is connected to the corresponding power mechanism through the lifting ring 2 for use. In this embodiment, two lifting rings 2 are provided, and the two lifting rings 2 are arranged on the left and right sides of the crossbeam 1 in a mirror-image manner. The bottom ends of the lifting rings 2 are fixedly connected to the top surface of the crossbeam 1. The two lifting rings 2 make the connection between the sling and the crane more secure when in use, the force applied during lifting is more balanced, and the lifting is also more stable. Two corresponding lifting groups are provided on the front and back sides of the crossbeam 1. The two lifting groups have the same structure, and each lifting group contains multiple lifting arms 3. In order to make the balance of the sling better, the two lifting groups contain the same number of lifting arms 3, and the lifting arms 3 of the two lifting groups correspond to each other in pairs, and the multiple lifting arms 3 of the same lifting group are connected in series through corresponding connecting rods 4. , multiple parallel corresponding booms 3 are evenly distributed on the connecting rod 4, and the booms 3 are fixedly connected to the connecting rod 4, so that the booms 3 of the same boom group all move synchronously, and the top of the boom 3 is connected to the beam 1, and a corresponding shaft sleeve 7 is provided at the connection between the two. The axis of the shaft sleeve 7 coincides with the axis of the beam 1, and the two are rotatably connected by the shaft sleeve 7. Both booms can rotate around it with the beam 1 as the axis. In this embodiment, each boom group is provided with two booms 3, and the two groups have a total of four booms 3. The tops of the two booms 3 of each boom group are rotatably connected to the corresponding two ends of the beam 1, and the tops of the two corresponding booms 3 at the same end of the beam 1 in the two boom groups cross each other, and the two are connected in series to the top of the corresponding beam 1 through the corresponding shaft sleeve 7. A corresponding support plate 6 is provided at the bottom end of the boom 3. When in use, the sling transports steel through the support plate 6.

[0016] The top of the support frame 31 is provided with a support plate 6, and the bottom end of the support frame 31 is detachably connected to the outer side of the upper surface of the support frame 6. When in use, the end of the thin plate is placed on the inner side of the vertical rod 31 on the upper surface of the support plate 6. The thin plate is supported by the support plate 6.

[0017] The connecting rod 4 includes an upper connecting rod 41 and a lower connecting rod 42. The upper connecting rod 41 connects the diagonal rod 32 of the same hanging group boom 3 in series, and the upper connecting rod 41 is vertically connected to the side wall of the diagonal rod 32. In this embodiment, the two ends of the upper connecting rod 41 are respectively vertically fixed on the two inner side walls of the corresponding hanging group boom 3. The lower connecting rod 42 connects the vertical rod 31 of the same hanging group boom 3 in series, and is vertically connected to the side wall of the vertical rod 31. In this embodiment, the two ends of the lower connecting rod 42 are respectively vertically fixed on the two inner side walls of the corresponding hanging group boom 3. The connecting rod 4 connects the boom 3 of the same hanging group in series, so that the strength of the hanging group is higher and the force it can withstand is also greater.

[0018] When in use, the support plate 6 of the sling is aligned with the appropriate position around the thin plate to be transported, and the support plate 6 is inserted under the thin plate so that the upper surface of the support plate 6 and the corresponding lower surface of the thin plate are in contact with each other. At this time, the external force-applying device applies force to the sling through the lifting ring 2, and the corresponding two lifting groups rotate in the front and rear directions of the thin plate with the crossbeam 1 as the axis under the action of their own gravity and the weight of the thin plate, thereby applying two corresponding front and rear forces to the thin plate, and then clamping and fixing the thin plate on the support plate 6 to prevent it from falling to the side during transportation. The sling drives the thin plate to a certain height under the action of the force-applying device. During this process, the sling applies an upward pulling force to it from the bottom of the thin plate through the support plate 6, thereby lifting the thin plate, and then transporting it to a suitable position and placing it for subsequent transportation and use.

[0019] The sling for transporting steel plates of the present invention is symmetrically distributed around the bottom of the thin plate through the support plates 6, and the force application point of the sling when lifting the thin plate is changed from point contact to surface contact. The four support plates 6 are lifted synchronously, and force is applied evenly to the thin plate. The lifting point of the thin plate and the bearing point are located on the same plane, so that the force point of the thin plate is stable, and the thin plate is not easy to fall or break during the lifting process, which reduces its damage rate during the lifting process, can make the lifting of the thin plate more stable and safe, and its lowering process is also safer and more reliable. The support plates 6 are supported at the bottom of the thin plate stack, which is convenient and quick to assemble and disassemble, and simple to operate. There is no need to use chains to pass through the bottom of the thin plate stack, and the edge of the stack will not be deformed by the squeeze of the chain, which avoids the deformation of the thin plate stack during the lifting process. The reinforcement plate enhances the stability of the boom 3. The use of the new sling is more time-saving and safer.
